２０とを具備して成っている。More specifically, the sheet metal puller 1 includes a pair of legs 2, 2 having contact surfaces 3, 3 that can contact the sheet metal surface 30,
A support rod 5 slidably supporting the leg body and having a through hole 6 for guiding the movable rod 15 in a direction perpendicular to the longitudinal direction at the center thereof; And a pair of operating arms 10, 10 pivotally supported, are positioned orthogonal to the longitudinal direction of the support rod 5, are inserted into the through holes 6, and are movable by the operation of the operating arms 10, 10. A movable rod 15 and one end thereof are attached to the operation arm 10,
It has a connecting rod 20 whose other end is pivotally connected to the movable rod 15 side.

原理的に優れた引出し作用を有しているといえる。Such a sheet metal puller 1 has a relatively simple structure, and is provided in a sheet metal puller (shown as a conventional example in FIG. 11 of the above-mentioned publication) which is pulled out by hitting with a conventional slide hammer. In comparison, it can be said that the use of a large number of washers (see FIG. 7 in the above-mentioned publication) welded to the metal surface of the concave portion has an excellent draw-out action in principle.

されることを目的とするから、現在の自動車が使用して
いる高張力鋼板に対しては必然的に高強度が要請され、
材質は金属製となって不可避的に重くなるという欠点が
ある。However, since the above-mentioned sheet metal puller 1 is intended to be mainly used for sheet metal drawing work of automobiles, it is inevitable for high-strength steel sheets currently used in automobiles. High strength is required,
There is a disadvantage that the material is inevitably heavy because it is made of metal.

【００１２】また、高張力鋼板は復元力が高く薄いの

引き出す細心の注意を要する。即ち、板金面３０の凹部
３５周辺に回動片４，４の接面部３，３の位置を定める
作業は慎重に行う必要があるのである。Further, since the high-tensile steel sheet has a high restoring force and is thin, it is necessary to pay close attention to the pulling (roughing) work while keeping the balance. That is, the operation of determining the positions of the contact surfaces 3, 3 of the rotating pieces 4, 4 around the concave portion 35 of the sheet metal surface 30 needs to be performed carefully.

ない。FIG. 4 seems to be a simple drawing operation of the sheet metal, but the positions of the legs 2 and 2 are adjusted so that the rotating pieces 4 and 4 appropriately contact the concave portions of the target sheet metal. Is adjusted, the movable bar 15 is adjusted, the attachment 36 is engaged with the washer 40, and then a series of pull-out operations for applying force so that the operating arms 10, 10 are strongly closed with both hands are performed by the sheet metal puller 1 itself. It is not easy because it is quite heavy.

面部の凹部の板金引出しである。For example, the sheet metal puller 1 is placed on the sheet metal surface 30 placed substantially in a horizontal plane as shown in FIG. Although the drawing operation can be performed, the sheet metal drawing operation of the concave portion of the side portion as shown in FIG.

たとは言えないのが現状であった。However, as shown in FIG. 5, the operator performs the above-mentioned preparation work while supporting the sheet metal puller 1, and then pulls out the target concave portion by applying a force in the direction of the arrow with both hands. When the pulling action force is applied to the turning pieces 4 and 4 to strongly press the sheet metal surface 30, the operator does not need to separately support the sheet metal puller 1, and only in the direction of the arrow as shown in the drawing. The force may be applied, but the operator must always support the sheet metal puller 1 itself until the state is reached, and furthermore, the operation arms 10, 10 which are far from the center of gravity have the ends. As a result, the burden of support has increased, and workability has never been easier.

An object of the present invention is to provide a sheet metal drawer that can easily perform an operation (particularly, an operation in a preparation stage).

である。As described above, the contact surface 65 of the sheet metal pull-out tool 50 with respect to the metal surface 30 of the concave portion of the automobile J to be repaired.
The sliding fixation, angle adjustment, etc. are performed, but at the time of work, at most, only a force of slightly lifting the leg portion 62 up and down with respect to the support rod 61 is required, and it is fixed in an appropriate position. Since the hand can be released, the work of pulling out the concave portion by applying the actual attachment 70 is greatly facilitated.

が均等になるようにすることができる。Second, the legs 65, 65, which are two independent legs which are fitted at right angles to the support rod 60 at one end and are slidable and can be fixed at an arbitrary position, are suitably provided. By adjusting the position around the concave portion of the target sheet metal surface, the stress applied to each contact surface portion 61 of the four rotating pieces 66 when the concave portion is pulled out can be made uniform.

After the positioning of the rotating piece 66 is completed, the tip hook of the chain 72 of the attachment is hooked on the substantially central portion of the metal rod passed through a series of washers welded to the concave portion, and the screw (ratchet screw) 71 is gradually attached. Turn to apply the traction force as evenly as possible to the recess and pull it out.

し作業が格段に容易になるという優れた効果を有する。As described above, the sheet metal drawer according to the present invention has the above-described structure, and therefore, the operation of adjusting the rotating piece, which is to be pressed against the target metal surface, to the optimum position reduces the weight of the sheet metal drawer itself. It can be performed without the support of the operator, and has an excellent effect that the draw-out operation becomes much easier.
